i swear i dont mean to nit pick and I know yall are not finished, but are the uppes bars at a decline towards the front at all? and can you get more pics of the front mount, I can't tell if yall are done with that portion or not. the work looks top notch though, welds all look good.
if possble, I would box that frame rail in where yall have the 4 link tabs welded up. just for safety.

Well to answer your question about if the upper bars or at a down angle..that would depend on where the truck is at the moment...if it is up or down. You are putting WAY TOO MUCH engineering into this. The article you posted is fine and would apply if AIR BAGS had a constant Compression Ratebut they do not. So depending on how much air you have in your bags depends on where your instant center is. That article is dependant on a coil spring that has a constant Compression Rate.I have built multiple Race cars that depend on all the aspects of the article that you posted but they all had Specific Coil Spring Compression Rates. As far as safety Concerns if ya wanna but truley safe then DON'T bag a truck. Dragging a truck is not safe, What if an air line blows, What if a bag Blows...there are so many none safe aspects of Bagging a truck the suspension angle of the bars is at the bottom. I even built a Maxda one time that hit a full sixe Dodge pick-up head on destroyed the truck but not one part of the suspension was damaged. They used it on another truck. It did in fact break the rearend in half.

You set your suspension geometry at half travel, so you have a fairly constant attribute. I ride at 1/2 travel so for me that is ride height and I don't ride low low unless i'm at a show or just want to be a show off on the highway. I'm not doubting your work, but I will stand strong in saying there are things to take into account in suspension design when building any form of car or truck. Spring rate a such is honestly worthless as you said, but the geometry is not, at all, worthless. I've seen trucks where the pinion angle changes more than 15 degrees through the trucks suspension travel, i've seen drive-shafts drop from broking a u-joint, and numerous other horror stories from bad geometry.
I simply asked if you took instant center into account as it tends to affect pinion change through travel the most on bagged rides and it's torture on the trucks if it changes too drastically. Again, I wasn't bashing your work or the truck itself. I was looking out for certain things I look at on every truck I take a peak at and wondered as it wasn't obvious.

On a bagged truck that is about the only thing I worry about is Pinion Angle Change. I try to set mine up so that there is less then 3 degrees of change and that at the mid point that the Pinion Angle and Drive shaft are at 0. That way there is no hard pressure on the U-Joint. You are right on that a broke drive shaft can be devistating. I was at the Drag strip one time and saw a car break one at the Transmission & sent the car into the air about 10 FT. NOT A PRETTY SIGHT. Especially at over 100 mph. But as far as I have learned in all the tucks that I have built most of that article on instant center, Roll-oversteer, Roll-understeer can really just be thrown out the window. Bags react so different and are rarely at the same pressure and then placement of the bag makes a difference too. So IN MY OPINION about the only large concern in putting on a 4-link is 1) Pinoin Angle, 2) Securly mounting all hardware, 3) Clearance issues.
